Riccardo Muti: 71, music director of the Chicago Symphony

"When I was a boy, I was crazy about the Platters and even now my grandson loves to listen to the Platters, especially 'Only You.' I don't often have time to listen to music off the podium, but I have always been impressed by Celine Dion, Tina Turner [pictured] and (the late) Whitney Houston for their fiery temperament and beautiful voices."
